Of course there are plenty of artists and such too, it's really hard to narrow to just 10. But I think people who made an attempt to understand the world around them would get the most out of another attempt.

Science1 Darwin (ahead of Einstein cos so many people still dispute Darwin, and he would have loved to find out about genetics)2 Einstein3 Galileo- not the best scientist – but he really should get a complimentary trip to the space shuttle4 Da Vinci(not really a scientist)

Arts5 Mozart (ahead of the others because he died young and was just hitting his straps – Beethoven really composed everything he could)6 Bach – cos you can’t get enough7 John Lennon (more for amusement value)
